About BQ500414 Frequency shift

Hi.

I use the USB INTERFACE ADAPTER to control frequency shift with the BQ500414-EVM and our BQ500414 board.

I put the RX(51013B-EVM) with no load  on the TX.

It's frequecny is 160Khz,I set the frequecny to 190KHz.

But it can not change the frequecny from 160kHz to 190KHz,

But I push the TX(ON/OFF) buttom,the TX be turned off.

Both BQ5004141-EVM and ourBQ500414 are the same.

so the communication is ok with TX(BQ500414).

What's wrong with the frequecny shift application?

    Sorry to see that you are having problems with this feature. I have used the Frequency Shift application with our bqTESLA TX Tuning Tool and the bq500414 EVM with good results.
    I will contact you off line to work this problem.
